Would you please help me on the following :
I'd like to have a website running as a multisite :
1. using subdirectories ;
2. having the first/main site working as a portal that will displays and share content (pages, articles, users, menus...) form other subsites ;
3. using different theme for each subsite ;
4. running a social network on a subsite (first choice : BuddyPress, but why not Mingle ?).
My needs are like on this post :
What plugins, and/or which configuration would be the best ?
